A Great Falls elementary school initiated a "shelter in place" Monday afternoon as law enforcement sought a suspect from the ground and sky.

Great Falls officers reportedly made contact with the suspect, who was wanted on warrant, but the suspect fled on foot. The search sparked searches by patrol units on the ground, and a Customs and Border Protection helicopter.

Media Relations Officer and GFPD Sgt. Jim Wells said because the agency was available, Homeland Security helped in the search by air.

As of the 3 p.m. press briefing with police, the suspect had not been detained. No further information was available at the time.
